Low power level translating I2C-bus/SMBus repeater

The PCA9509A is a level translating I²C-bus/SMBus repeater with two voltage suppliesthat enables processor low voltage 2-wire serial bus to interface with standard I²C-bus orSMBus I/O. While retaining all the operating modes and features of the I²C-bus systemduring the level shifts, it also permits Bidirectional buffer isolates capacitance and allows 400 pF on port B of the device\nVoltage level translation from port A (0.8 V to 1.5 V) to port B (2.3 V to 5.5 V)\nRequires no external pull-up resistors on lower voltage port A\nActive HIGH repeater enable input disables current mirrors and curre;

Level translating I2C-bus/SMBus repeater

The PCA9509 is a level translating I²C-bus/SMBus repeater that enables processor lowvoltage 2-wire serial bus to interface with standard I²C-bus or SMBus I/O. While retainingall the operating modes and features of the I²C-bus system during the level shifts, it alsopermits extension of the I²C-bus by Bidirectional buffer isolates capacitance and allows 400 pF on port B of the device\nVoltage level translation from port A (1.35 V to VCC(B) ‑ 1.0 V) to port B (3.0 V to 5.5 V)\nRequires no external pull-up resistors on lower voltage port A\nActive HIGH repeater enable input\nOpen-drain inputs/outpu;
